Combined vertical and horizontal rope climbing apparatus
A combination horizontal and vertical rope-pulling device that uses a hydraulic braking assembly that is mounted on a vertical frame to support an endless rope that is placed over a number of pulleys. A pivoting boom is attached at the top of the frame. In the vertical mode, the rotating boom is positioned at an angle extending rearward from the vertical frame. The rope passes over a number of pulleys to simulate a vertical rope for climbing. In the horizontal mode, the rotating boom is rotated down so that it is parallel to the vertical frame. The rope follows the downward run of the boom and around the pulleys. In this way, the user can use the machine as a horizontal rope-pulling machine.

BACKGROUND OF THE INVENTION1. Field of the Invention
This invention relates to rope pulling apparatus and particularly to a combination vertical and horizontal rope pulling apparatus using endless ropes.
2. Description of the Prior Art
Pulling ropes have been a part of fitness gyms for many years. Rope pulling is an excellent exercise for the wrists, hands and upper body. Traditionally, these ropes have been long (20 foot) lengths of rope that were suspended from a gym ceiling. There are two problems with the traditional fixed rope as an exercise tool. First, there are few buildings used for gyms today that have high enough ceilings. Second, a 20-foot length of rope does not provide enough sustained effort to enable someone skilled in rope pulling exercise to receive a sufficient workout. Once a person has reached the top of the rope, he or she must descend before he or she can climb again.
To overcome these difficulties, endless rope exercise machines have been invented. These devices use a frame, an endless length of rope and a means of resistance to simulate actual rope pulling. Such machines enable a user to “climb” a rope for as long as the user's stamina permits. U.S. Pat. No. 5,076,574 discloses a portable rope pulling exercise apparatus that has a frame, a series of pulleys supporting a rope, and a hydraulic brake system to provide resistance for the rope.
In addition to vertical rope pulling machines, it is also desirable to have horizontal rope pulling machines that can simulate a tug-of-war. One example of such a machine is found in U.S. Pat. No. 5,318,491, which shows a machine that has a rope extending from a control box. The box has parts that adjust the tension of the rope and the pulling force. The user stands on a treadmill. As the user pulls on the rope, the user moves on the treadmill. Alternatively, the treadmill can be locked for static rope pulling. The problem with this machine is that it is bulky with the treadmill. Moreover, although this device can simulate a tug-of-war, such a simulation is not the best exercise that can be obtained using a pulled rope. Finally, the displacement of the rope is such that it is not guarded. Thus, it appears that when not in use, the rope is left lying on the treadmill, which is a tripping hazard. In addition, the rope is dispensed through two holes that are narrowly spaced apart. This can lead to discomfort when the rope is under tension, because the loop may close on the user's hands.
Another horizontal pulling machine is found in GB 2,341,806.
Although the vertical and horizontal machines exist, no machine combines the features of vertical and horizontal machines into one single machine. Such a machine can save space and lower costs by eliminating the extra machine.
BRIEF DESCRIPTION OF THE INVENTIONThe instant invention overcomes all of these problems. It is a combination horizontal and vertical rope-pulling device. The machine uses a hydraulic braking assembly that is mounted on a vertical frame to support an endless rope that is placed over a number of pulleys. A pivoting boom is attached at the top of the frame. The boom has a fixed member that spaces the rotating boom from the vertical frame. In the vertical mode, the rotating boom is positioned at an angle extending rearward from the vertical frame. The rope passes over an upper pulley, and then runs back to a first guide pulley. It then runs up over a second guide pulley, where it then drops down to the horizontal frame. It then passes through a trough in the horizontal frame. The rope then passes through the vertical frame and then back to a braking pulley.
In the horizontal mode, the rotating boom is rotated down so that it is parallel to the vertical frame. The rope follows the downward run of the boom. Here, however, instead of passing over the second guide pulley, the user pulls the rope back using the first guide pulley as a guide. As before, the rope passes down through the trough in the horizontal frame and then back to the braking pulley. In this way, the user can use the machine as a horizontal rope-pulling machine.
Referring now to
The horizontal frame 8 extends back from the vertical frame 52 as shown. It includes a top plate 10 and a seat 11. A support brace 8a elevates the seat 11 above the ground. Below the top plate 10 is a pair of plates 9 that frame a trough under the top plate 10. The top plate 10 has a slot 12 cut into it to allow the rope 4 to pass through as shown. The rope 4 runs down, under the top plate, through the trough, and through the vertical frame 52. It then runs to the pulley 5, completing the loop. The plates 9 can be made of metal or plastic.
This figure also shows the braking system from the right side of the machine. Here, the hydraulic motor 20, the reservoir 21, the hydraulic lines 22 and the control knob 7 are shown. The hydraulic motor 20 is connected to the drive pulley 5 by a shaft. As the control is adjusted, the hydraulic system increases the amount of force needed to turn the main cylinder and the drive pulley. This increased force translates to increased pulling resistance experienced by the user. In this way, the amount of energy needed to pull the rope can be adjusted as desired by the user.
